Wallboard joint construction



C. O. WALPER' WALLBOARD JOINT CONSTRUCTION Filed Aug. 27, 1954 v INVENTOR:

CURRY ORA ATTORNEM Patented May 26, 1936 UNITED STATES PATENT OFFICE Application August 27,

1 Claim.

This invention relates to wallboard and to joint construction therefor.

In the construction of Walls and ceilings of rooms it not infrequently happens that some of the studs of the frame are not erect in truly parallel relation with others, so that the front face of such studs is twi ted out of a plane parallel with the wall surface. This exposes an edge of the stud to engagement with the margin of one board, while the margin of the adjoining board meeting on the stud bears primarily on the central portion of the stud leaving the end of the first mentioned board projecting out of the plane of the wall. This affords difliculty in constructing a suitable joint and results in unevenness in the finished surface. When the wall is decorated these inequalities in its surface manifest themselves in an objectionable manner.

The object of the present invention is to overcome these difficulties and to provide a wallboard by the use of which such irregularities in the frame construction may be taken care of and an adesuate joint readily provided.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a sectional of the wall, and

Figure 2 is an enlarged sectional plan view of the joint.

In the drawing, I and 2 represent the studs of the frame, the central one 2 being shown out of alignment, 3 the usual sheeting on the outside of the studs and 4 and 5 wallboards erected on the inside of the frame. It will be observed that the meeting marginal edges of the wallboards are slightly inturned, the length of the plan view of a portion 1934, Serial No. 741,691

deflection being substantially equivalent to one half the width of the stud. The inturned margin 6 of the board 4 accommodates the projecting edge 1 of the stud and permits the margin to rest on the face of the stud to which it is secured by fastening means 8. The board 5 is likewise secured to the stud by the fastening means 8. The meeting marginal edges of the boards provide a depression in the joint area for the reception of joint filler 9 which smoothly fills the depression and. merges or feathers into the surface of the boards providing a uniformly smooth surface-in the wall.

In the erection of the wallboard 5, if desired, joint filler may be buttered on to the inner face of the margin I0 and on the inner end thereof to fill the spaces II and I2, respectively, and thus afford bearing surfaces over the full area of these faces of the marginal portions of the board. It will be appreciated that these spaces II and I2 will vary considerably depending upon the actual position of the stud.

The extent of the deflection of the margin of the board is not great and it does not interfere with the normal handling of the board.

I claim:

In construction of wallboards, each fixed at opposite sides to frame members, wherein the face of a frame member to which boards are fixed is not in a plane parallel with the plane of the main face of the boards, wallboards preformed along their edges to be applied to such frame member to curve toward such frame member out of the plane of the main faces of the boards.
